Application filed December 7, 1908. Serial No. 488,201.

' of pipes.

The object o'f the invention is to provide 'a simple and ellieientarrangement, of hog ie or truck for pipe foundry plants adapted tofacilitate the varioi'is ()lXl'tllilUHS neeessary in the manul aetnreand handling of the pipe l'n'oduel' to he produced.

()ther ohjeets o'r' the invention will appear more fully hereinafter.

The invention eousistssuhslaul 'ally in lhe mu'istruetion,eouihination.- oration and relative arrangement of para all as will hemore fully hereinafter set truth, as shown in the aeeonn'nmyiup:drawiwgs and finally pointed out in the amjemled claims.

lltelerring to the aeeom imnying drawings, and to the various views andreference signs appearing llll,itfltl,"l lglll'G l is a detached detail"view in side elevation partly l)l'(Il U1l oll' ol a pipe hox and, itssupporting hogie and embodying the princip s of my inven-' tion. l 'ig.same. Fig. 3 is a view similar to Fig. 1 showing another construction ofho'gie emoraeed within the scope ot my invention. Fig. 4 is a transversesection of the construction shown in Fig.

The same part is designated by the same reference sign. wherever itoeeurs tl'iroughout the several views.

In the practical operation of pipe foundries much time and lahor arerequired in the proper handlirg ot the molds and other parts of theapparatus required in thenianufaeture of pipes. The ap 'nui'atu employedis usually heavy and where several successive stages or operations arerequired, as for instance, the forming o'l the mold, drying it, theintroduction of molten metal to the llaslc or molding box, the removalof the east. pipe, and other operations ineident lo the manufaeture ofeast iron pipes, it is a serious problem to effect the shi'ltil'ig' ofthe [task carrying the mold to. the various 'points Where the variousoperations are earried out,

i is a transverse section of the espeeially where care must he observedin preventing injury to the mold before the pipe is e we, and theseditliculties involve not only loss of time and the use of heavyexpensive shitting eranes and other inaehiner), hut also greatly reducethe daily caparity and output of the plant.

it is among the special purposes of my present invention to provide ahog'io or ll'lltll having sueh construction and arrangemen t. as tooreatly facilitate the manuliaeture o l pipes hy rendering the handlingand shifting of the flasks or molding boxes from point to point whererequired easy and rapid. and with-out the necessity for the use olcranes, "for; ell'eeting the shifting ,operallon.

in carrying out my invention 1 mount "the flasks or hoxes in which themolds are l'oruu-d and the castings are made, on'

'llt!()l((l supports or hogies, designed to operate on suitably arrangedtraek rails, the hogies heing so eoi'istrueted and arranged as to Form auiovahle support lor the flasks or mold hex, the latter heing supportedloy such hogies in vertieal position and depending below the level. ol?the traek rails on which tho wheels of the hogie operate. In practice,and preterahly, the pipe boxes are made in seetions and. the sectionsare mounted upon the. hogies or the axles thereof for movement, towardand away from CllCll other whereby they may he closed as retpiired toreceive the mold material and the molten metal, or opened to permit theren'ioval of the finished pipe. The track rails on which the hogiesoperate may have any saitahlo arrangen'ient and may he sumiorled in anysuitable manner. 4

In Figs. 1 and 2, l have shown ()llttlllilll of l)()X and itssupporting; hi'igie wherein-the box is made in z-eelions A, ll, eapahleoli movement toward and l'rom eat-h other upon the hogrio on which theyare suppor ed and suspel'ided, to open and ('lose the hes. in this formeaeh hox section is provided with the sleeves t, on opposite sidesllHlVUl lilied to slide upon the axles o, ol' the hogle, the hogiewheels l), heiue mounted on the ends oli said axles. ll desired the axls may he slotted lo rem-ive the eoller wedges ll, hy means ol which thehex sections are (damped together and l'aslened. lly removing these(roller wedges the hex seelions may he sepa rated to open the hon. lu lies. 33 and l, l' have shown another size and style of pipe By removingthe cotter Wedge E, in the one case, and L, in the other, the sectionsof the boxes may be moved from each other to open the boxes and permitthe removal of the contents thereof. In the construction shown in Figs.3 and 4, the rods H, which support the box sections are arranged atright angles to the axles, and by removin said rods the box sections may.be replaced by others of different size.

From theforegoing description it will be seen that I provide anexceedingly simple and eflicient arrangement for handling the pipe boxesand for supporting and transporting the same.

Having now set forth the ObJGCt and nature of my invention andconstructions and arrangements embodying the principles thereof, what Iclaim as new and useful and of my own invention and desire to secure by.

Letters Patent is 1. In a molding plant, a bogie or 'truck havingsupporting wheels, a pipe molding box or flask made in sections, saidsections being supported on the bogie or truck in vertical position formovement toward and from each other to open and close the box or flask.I

2. In a molding plant, a bogie or truck having supporting wheels, a pipemolding box made in sections,}said sections being suspended andsupported in vertical position on said bogie or truck for movementtoward and from each other, and means for locking said sectionstogether.

3. In a foundry plant, a bogie, a pipe molding box dividedlongitudinally into halves and mounted on said bogie for move menttoward and'from each other and means for locking said halves together.

4. A bogie or truck for moldin plants having supporting wheels, in comination with a pipe molding box made in sections, said sections havingsleeves whereby they may be suspended in vertical position upon thebogie or truck for movement toward and from each other, and means forlocking the sections together.

5. A bogie "or truck for molding plants having supporting wheels, incombination with a pipe molding box made in sections,

horizontally arranged supports carried by said wheels, said sectionsbeing suspended in .vertical position upon said supports for movementtoward and from each other, and

means for locking said sections together.

6. A bogie or truck for molding plants having supporting wheels, a framecarried.

by said wheels, supporting rods carried by said frame, a pipe moldingbox made in sections, said sections being suspendedin vertical positionupon said rods, for movement toward and from each other and means forlocking said sections together.

7. A bogie or truck having supporting wheels, a pipe anolding box madein sectio capable of being closed to receive the mo d and the moltenmetal, and of being opened to remove the mold and pipe castingtherefrom, said box sections held in vertical position on said bogie ortruck, and means for opening and closing said pipe box-sections.

In testimony whereof I have hereunto set my hand in the presence of thesubscribing witnesses, on the 21st day of October A. D., 1908.
